Plainsboro PD frequently has a patrol car set up behind the ‘Marriott’ sign on Route 1 North, just before the College Road exit ramp. The car is EXTREMELY well hidden, usually angled so that motorists cannot see it until it’s basically too late (less than 100 feet away.) The flow of traffic in this area is usually 63-70mph, but if you go above that (and, especially, if you have out of state license plates), you run the risk of getting pulled over. Since the car is so well hidden, this spot is used for both daytime and night enforcement.
